Broom-angle Lever squeezed. This allows for easier turning and maneuvering the machine (Figure 6). The broom-angle lever is located at the right handle (Figure 6). Note: Squeezing both wheel clutch levers simultaneously disengages the drive to both wheels (free-wheeling). This enables you to manually move the machine backward without stopping to shift it into a reverse gear. It also allows you to maneuver and transport the machine more easily when the engine is not running.
Operation DANGER When fueling, under certain circumstances, a static charge can develop, igniting the gasoline. A fire or explosion from gasoline can burn you and others and damage property. Fueling the Machine • Fuel tank capacity: 4.1 L (1.0 US gal) • Recommended Fuel: • Always place gasoline containers on the ground and away from your vehicle before filling.
Operating the Engine Positioning the Air-cleaner Cover for Cold or Warm Air Temperature Important: Running engine with air-cleaner cover positioned for cold weather operation in normal conditions can damage engine. The air-cleaner cover has 2 position: the cold- or normal-ambient air positions: Adjust the air-cleaner cover as follows: • When operating in a cold ambient air condition (cold Figure 9 air temperature and humidity)—position the air-cleaner cover with snowflake decal facing out (Figure 8). 1.
Note: If the ground speed is too fast, debris or snow will pile up in front of the broom causing the broom to bulldoze instead of sweep. This can damage the bristles and the drive line. 4. Slowly pull the engine-recoil handle until you feel resistance and then stop. Allow the recoil handle to return and then sharply pull it straight out (Figure 10). Note: Allow the rope to return slowly. 2. Slowly squeeze the left hand traction drive lever to the handle (Figure 12). 5.
WARNING Contact with a rotating broom can result in serious personal injury or death to the operator or bystanders. • To remove an obstruction from the broom; refer to Clearing a Clogged Broom (page 16).
